The problem that a group e.g. of collaborating EXO-fans are permitted to edit jointly e.g. such a listing of EXO resources, is still unsolved. Good ideas are highly appreciated. This post is just a placeholder and should eventually be replaced by the real thing.

Perhaps the moderator could try keeping the listing up-to-date until we have found a better solution?

i would have thought that there would be a "group" permission like the "owner" and "other"

now a 777 would not be good but a 664 would

but i have not played with phpbb so...

Perhaps you slightly misunderstood: we are working to bring such a group permission into operation. But so far it seems that this issue remains still unsolved within the phpbb framework (unless everyone gets moderator rights ). Until a solution is found, we would therefore ask the moderators to update the scientific resource listings... Thanks!

When I asked "Nothing new?" above I was alluding to the fact that the science media currently publish at full load about our Sun's older twin, HIP 102152, while here nothing was even mentioned...

In terms of mass, temperature and chemical composition, the star HIP 102152 located at ~ 250 ly distance, is the closest match to our Sun ever found! But it’s also almost 4 billion years older, providing a most revealing glimpse of what might happen to our 4.6-billion-year-old sun as it ages.

++++++++++++++++++++++++++++++++++++++While this story has not yet led to direct evidence for EXO planets around HIP 102152, the quest for the existence and properties of possible planets and their comparison with those of our Sun seems most exciting and definitely worth being watched in this new department!++++++++++++++++++++++++++++++++++++++

Note that like the Sun, HIP 102152 has relatively low amounts of iron, magnesium and silicon, elements that tend to make up the bulk of the mass of rocky planets such as Earth. That could be a first (indirect) sign that the newly discovered star hosts planets.

The story about the Lithium content is also very illuminating (statement by lead author TalaWanda Monroe):"The group found that HIP 102152 has very low levels of lithium. This demonstrates clearly for the first time that older solar twins do indeed have less lithium than our own sun or younger solar twins. We can now be certain that stars somehow destroy their lithium as they age, and that the sun's lithium content appears to be normal for its age.”

Anyway, here are a couple of interesting links to original papers (available to everyone):

I particularly like the latter news and presentation. It's cute to correlate the transit depth (and hence the apparent planetary radius (fraction)) in various colors with the amount of atmospheric Rayleigh scattering at respective wavelengths.

Previous studies like Bonnefoy et al (2013) have suggested the mass of the companion to κ And could be much higher than first suggested by J. Carson et al (2012). The mass of the companion no longer appears to be in the planetary regime.

Planetary systems seem to be truncated in multi-stellar systems with separations less than 10 AU, suggesting the presence of such a close companion star interferes with planet formation. Also, four KOI planets are validated.

Another candidate planet from microlensing. This is the first time a planet has been found from microlensing using a pure survey technique as opposed to alerting other assets to assist in observing when a microlensing event is first detected.
